Hong Kong runs live trial of wholesale CBDC

The Hong Kong Monetary Authority ran a live market trial of a wholesale central bank digital currency in Hong Kong. The exercise placed digital reserves with eligible banks and market infrastructure providers for use in real market transactions under controlled conditions.

Participating institutions used wholesale CBDC balances to settle interbank fund transfers and the settlement leg of tokenized securities trades, testing same-day settlement mechanics and settlement finality.

The pilot linked a CBDC ledger with existing market systems to verify the delivery of central bank money across distributed ledgers while maintaining regulatory oversight and reconciliation processes.

Organizers recorded settlement speed, the reliability of atomic settlement between payment and securities legs, the impact on intraday liquidity needs, and the effectiveness of risk controls.

Transactions occurred among real counterparties using live operational systems but within a limited, supervised scope to contain operational risk. The controlled exposure enabled testing of edge cases and error recovery procedures without disrupting broader market functioning.

Technical work during the trial focused on interoperability with banks’ internal systems and market utilities, moving tokenized assets using a common digital cash instrument, and operational questions for nodes or validators on distributed ledgers.

The pilot also examined access criteria for eligible institutions and safeguards for auditability and compliance with anti-money-laundering and know-your-customer requirements.

Findings from the trial will inform policy decisions on whether to broaden wholesale CBDC functionality and on changes needed to legal frameworks, operational protocols and industry standards before any wider implementation.

Wholesale CBDC is issued to regulated financial institutions for interbank settlement and is not held directly by consumers. Central banks globally have conducted similar experiments to explore faster settlement, improved liquidity management and more efficient cross-border payments while monitoring effects on financial stability and monetary policy transmission.

The monetary authority plans to publish a summary of the trial’s technical and operational lessons and to engage with industry participants on next steps.
